Specification of Letters Patent.

Fatented Dec. 24, 1907.

Application filed August 12. 1907- Serial No. 338,192.

To all whom it ma'y concern:

Be it known that 1, LEE S. STRAIGHT, a citizen of the United States, residing at Fonda, in the county of Pocahontas and State of Iowafhave invented a new and useful ()onveyer, Dfwhich the following is a specification.

This invention relates to endless conveyers and has for its object to provide a strong, j durable and thoroughly efficient device of} this character especially designed for con-l veying bricks, tiles, hollow ware and the like I to a kiln and also for removing the bricks or other articles from the kiln after the same have been burned or baked.

A further object of the invention is to provide a portable conveyer including a truck having an endless chain mounted for rotation thereon and provided with a plurality. of cars-ada ted to receive the bricks, tiles or other artic es to be transferred, said chains 1 being operatively connected with a motor or other source of power carried by the truck.

A further object is to provide means for elevating the forward end of the conveyor so as to permi t the discharge of the load at any desired height, and means for )reventing accidental displacement of the load when elevating or transferring the latter.

A still further object of the invention is to to increase t cienoy.

Further ob ects and advantages will apieir utility, durability and ei'li understood that various changes in form, proportions and minor details of construc tion may be resorted to within the scope of the ap ended claims.

In t 1e accompanying drawings forminga part of this specification 1' Figure 1 is a side elevation of an endless conveyor constructed in accordance with my invention. Fig. 2 is a top plan view of the same, a portion of the 1 i l i l I end ess chain being broken away to show] the construction of the truck and its associj ated parts. Fig. 3 is a transverse sectional View taken on the line 3-3 of Fig. 1. Fig.

4 is asectional view of one of the load supporting cars. Fig. 5 is an enlarged top plan view of one of the cars. Fig. 6 is a detail iew illustrating the jointhetween the main and auxiliary track sections.

Similar numerals of reference indicate corresponding parts in all of the figures of the i I rear end of the truck, the trea The improved conveyer forming the subject matter of the present invention is preferably mounted on a truck having front and rear axles 5 and 6 connected by spaced longitudinal side inembers or bars 7, the op osite ends of which are referably exten ed longitudinally beyond tie wheels of. the adjacent axles, as shown.

Bolted or otherwise rigidly secured to the side members 7 are spaced u rights or standards 8 to the upper ends of w ich are secured the main track sections 9. The track sections 9 are referably formed of angle iron and are inc ined downwardl towards the (f surface of the angle iron being provided with vertically disposed guide flanges 10 for the urpose hereinafter referred to. Pivotal y connected with the forward or elevated ends of the main track sections 9 are auxiliary track sections 11 also referably formed of angle iron and provided with guide flanges similar in construction to the flanges 10. The adjacent ends of the track sections 9 and 11 are over-lapped and pivotally connected by a rod or bar 12 which engages an elongatedslot 13 formed in the adjacent end of the auxiliary track section 11, thereby to permit the auxiliary track sections to be adjusted vertically of the truck,

Secured to the side members 7 of the truck I at a point adjacent the forward truck wheels are vertically dis osed plates or brackets 13 in the free ends ofwhich is j ournaled a transverse shaft 14 carrying spaced sprocket wheels 15 adapted to engage the sprocket chains 17 constituting the conveyer.

Pivotally mounted for swinging mov ment on the shaft 14 is a boom 18 having its upper or free end provided with terminal slots 19 in which are mounted bearing blocks 20, said blocks being adjustable longitudinally of the slots by means of adjusting screws 21 threaded in plates 22 carried by the free end of the boom.

Journaled in the bearing blocks 20 is a transverse shaft 23 carrying s aced sprocket wheels 24 which engage the o ains 17 of the conveyor, said chains being also enga edby similar sprocket wheels 25 mountef on a shaft 26 extending transversely of the truck 1 at the rear end thereof, as shown.

Disposed at spaced intervals on the sprocket chains 17 are a pluralit of cars 27 adaptedto receive-the bricks, ti es or other articles to be transferred.

4 of angle iron and journale 11 and bear against the guide flanges 10. so as i to prevent accidental displacement of said ears.

Extending vertically from the rear end of each car is a rest or support 31 which receives the load and retains the same in position on the car when elevating or otherwise transferring the same.

Extending longitudinally of the truck and bolted or otherwise rigidly secured to the inner faces of the side bars 7 are angle irons 32 which form tracks or supports for the cars after said cars have been relieved of the load.

Mounted on the bed or platform 33 of the truck is a motor, engine or other suitable source of power 34, said motor being con nected to a master wheel 35 through the medium of a belt 36. The master wheel 35 is keyed or otherwise rigidly secured to apower shaft 37 journaled insuitable bearings on the side members 7 of the truck and provided with a terminal pinion 38 which meshes with a gear 39 carried by a corres ending shaft 40 referably disposed para lel with the sha t 37, as shown.

Secured to the central portion of the shaft 40 is a sprocket wheel 41 having a sprocket chain 42, the latter being also connected with.

a sprocket wheel 43 secured to the central portion of the transverse shaft 26 so that 5 power may be transmitted from the motor 34 through the medium of the belt and intermediate gearing to the endless conveyer or chain. I

As a means for taking up the slack in the belt 36 there is provided an auxiliary platform 44 interposed between the platform 33 and the base of the motor 34, said auxiliary platform being formed with a vertical lip 45 in which is threaded adjusting screws 46, the latter being operatively connected with the base of the motor so that by adjusting the screws '46 the motor may be shifted longitudinally of the auxiliary platform and thus tighten the belt.

Extending vertically from the forward end of the side members 7 are relatively short standards 47 in the free ends of which are journaled suitable rollers or p ullcys 48.

Depending from the boom 18 at the standards 47 are inclined arms 49 to the free ends of which are attached suitable ropes or cables 50 which pass over the rollers 48 and are operatively connected with a windlass 51 so that by rotating the crank 52 the auxiliary track section 11 may be adjusted vertically of the truck so as to permit the discharge of the load at any desired height.

l wheel 53 the teeth of which are engaged by a locking awl 54 pivotally mounted on the standar 47 so that the auxiliary track section may be locked in adjusted position.

I 'The axles of the cars 27 are preferably extended beyond the adjacent wheels or rollers j 13 and are pivotally connected with the links of the sprocket chains 17 whereby the cars are maintained at the proper distance from each other.

In operation the motor is started and the 1 cars successively loadedby placing the bricks, 1 tiles or other articles in position on the cars '1 with the load bearing against the vertical rests or supports 31. As the endless chains are rotated the load of each car will be successively discharged at the upper or free end of the conveyer and said cars caused to travel downwardly and rearwardly into engagement with the lower tracks or angle bars 32 to the rear end of the conveyer and in positionto receive another load.

In order to adjust the height of the forward end of the conveyor it is merely necessary torotate the crank 52 in the manner before described, the slotted connection between the main and auxiliary track sections 9 and 11 permitting free movement of the operation.

chains and cars for elevating the load it is obvious that an endless belt having buckets or flights riveted thereto may be employed if desired, the result accomplished being the same in both instances.

From the foregoing description it is thought that the construction and operation of the device will be readily understood by those skilled in the art and-further description 1 thereof is deemed unnecessary. j Having'thus described the invention What is claimed is: l 1.
